The specific surface area of a powder is an important physical property, which refers to the total surface area (in square meters) of an oxide powder per unit mass (in grams). The size of the specific surface area is related to factors such as particle size, shape, and porosity of the powder. Generally speaking, the smaller the particles and the higher the porosity, the larger the specific surface...

The preparation method is one of the key factors affecting the specific surface area of oxide powders. Different preparation methods can lead to differences in the size, shape, and porosity of powder particles, thereby affecting their specific surface area. For example, the sol gel method can prepare oxide powders with high specific surface area, uniform particle size and fine size; The co precipi...
